it's not warm when she's away

Night or day, this solar power plant always turns us on

If you live on a rotating planet or have ever heard Bill Withers, you know solar power has its limits. We need electricity even after clouds roll in or the sun goes down (unless you’re a goth and enjoy total darkness).

Which is why an award-winning solar project in Spain is so awesome. The Gemasolar plant can store 15 hours’ worth of heat, which means it’s regularly able to produce energy around the clock. The plant delivered energy 24/7 for 36 days straight in 2013.
